In a liquid, molecules attract each other equally in all directions, but those at the surface experience an imbalance—they are pulled inward by neighboring molecules but not outward by the air above. This creates an invisible “film” at the surface that resists external force and minimizes the liquid’s surface area. Surface tension explains why smal
